C =$1.75 be where c represents the cost of in dollars and be represents the number of boxes of crackers

Answers

Final answer:

The question is asking about the relationship between the cost of crackers in dollars (c) and the number of boxes of crackers (be)

Explanation:

The subject of this question is Mathematics. The question is asking about the relationship between the cost of crackers in dollars (c) and the number of boxes of crackers (be). It seems that c represents the cost in dollars and be represents the number of boxes of crackers. The question is asking you to find out what the cost of 'be' boxes of crackers would be.

You are setting up a zip line in your yard. You map out your yard in a coordinate plane. An equation of the line representing the zip line is y=2x+4y=2x+4. There is a tree in your yard at the point (−4, 11)(−4, 11). Each unit in the coordinate plane represents 1 foot. Approximately how far away is the tree from the zip line? Round your answer to the nearest tenth.

Answers

Solving this problem needs the distance formula of point to a line.

The formula is:

distance = | a x + b y + c | / √  (a^2 + b^2)

 
So we are given the equation: y = 2 x + 4

Rewriting this would be: y – 2 x – 4 = 0 ->  a = -2, b = 1, c = -4

 We are also given the points:

(-4, 11) = (x, y)

 Plugging it in the distance formula at points (x, y):

distance = | -2 * -4 + 1 * 11 + -4 | / √ [(- 2)^2 + (1)^2]

= 15 / √ (5)

= 6.7

 So the tree is approximately 6.7 feet away from the zip line.

Since cc is on the right side of the equation, switch the sides so it is on the left side of the equation.6(2c−12)−4c=8(c−9)6(2c-12)-4c=8(c-9)Simplify the left side.8c−72=8(c−9)8c-72=8(c-9)Simplify the right side.8c−72=8c−728c-72=8c-72Move all terms containing cc to the left side of the equation..−72=−72-72=-72Since −72=−72-72=-72, the equation will always be true.Always true
On the left side of the equal sign, multiply everything in the parenthesis by 8.
On the right side of the equal sign, multiply everything in the parenthesis by 6.

8c - 72 = 12c - 72 - 4c

Combine like terms.

8c - 72 = 8c - 72

Add 72 to both sides.

8c = 8c

Subtract 8c from both sides.

0 = 0

This means that there is an infinite amount of solutions.

Joesl's father is 45. He is 15 years older than twice joe's age. How old Is joe?

Answers

Joe father is 45

Joe father is 2x + 15

2x + 15 = 45
2x + 15 (-15) = 45 (-15)
2x = 30
2x/2 = 30/2
x = 15

Joe is 15

hope this helps
So, you make your equation 2x+15=45, because of the given numbers. Now you solve for x.
First, you subtract 15 from both sides, which gives you 2x=30.
Then you divide both sides by 2, which give you x=15.
So, Joe is 15 years old.

Find the equation for the table

Answers

(10,337),(15,340)
slope = (340 - 337) / (15 - 10) = 3/5

y = mx + b
slope(m) = 3/5
(10,337)....x = 10 and y = 337
now we sub into the formula and solve for b, the y int
337 = 3/5(10) + b
337 = 6 + b
337 - 6 = b
331 = b

so ur equation is : y = 3/5x + 331 or 3x -5y = - 1655

Answers

I hope this helps

g(x)=3x-6

Answer:

The graph of g(x) is the result of translating the graph of f(x) = 3x six units to the right

When a graph is shifted 'a' units to the right f(x) becomes f(x-6)

Given f(x)= 3x

When graph is shifted 6 units to the right , then g(x)= f(x-6)

Replace x with x-6

g(x)= 3(x-6)= 3x-12

so g(x)= 3(x-6)

The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the shirts they ordered, to earn a total of $1,750. After the first week of the fundraiser, they sold  1/3 of the short-sleeved shirts and  1/2of the long-sleeved shirts, for a total of 100 shirts.
This system of equations models the situation.
   5x + 10y = 1,750
1/3x + 1/2y = 100
Let x represent the number of short-sleeved shirts ordered and let y represent the number of long-sleeved shirts ordered.
How many short-sleeved shirts were ordered?

How many long-sleeved shirts were ordered?

Answers

150 short-sleeved shirts
100 long-sleeved shirts

Answer:

150 short-sleeved shirts and 100 long-sleeved shirts.

Step-by-step explanation:

We will use elimination to solve this system of equations.  We will make the coefficients of x the same in order to eliminate them; to do this, we must multiply the bottom equation by 15 (1/3 of 15 is 5, so 15(1/3) = 5):

[tex]\left \{ {{5x+10y=1750} \atop {15(\frac{1}{3}x+\frac{1}{2}y=100)} \right. \\\\\left \{ {{5x+10y=1750} \atop {5x+7.5y=1500}} \right.[/tex]

Subtract the second equation from the first one:

[tex]\left \{ {{5x+10y=1750} \atop {-(5x+7.5y=1500)}} \right. \\\\2.5y=250[/tex]

Divide both sides by 2.5:

2.5y/2.5 = 250/2.5

y = 100

Substitute 100 in for y in the first equation:

5x+10(100) = 1750

5x+1000 = 1750

Subtract 1000 from both sides:

5x+1000 - 1000 = 1750 - 1000

5x = 750

Divide both sides by 5:

5x/5 = 750/5

x = 150

40 pounds of sugar are repackaged of 1/16 pounds each. how many packet of sugar are there?

Answers

We know to each pound of such, there is 16 packets produced per?

So, 16 x 40 = 640.

Final answer:

To find the number of sugar packets from 40 pounds, divide by the weight per packet (1/16 pound). The calculation is 40 divided by 1/16, resulting in 640 packets.

Explanation:

To determine how many packets of sugar you can make from 40 pounds of sugar when each packet is 1/16 pounds, you would divide the total amount of sugar by the amount each packet contains. This is a basic math problem involving division.

Here's the calculation:

First, we establish that there are 40 pounds of sugar that need to be divided into packets.

Next, since each packet will contain 1/16 of a pound of sugar, we divide the total pounds of sugar by the weight of each packet.

The calculation is 40 pounds \/ (1/16) pounds per packet, which simplifies to 40 × 16 packets.

After performing the multiplication, the result is 640 packets of sugar.

Therefore, you would have a total of 640 packets of sugar if you repackage 40 pounds of sugar into 1/16 pound packets.

Corey has 16 cups of flour to make cookies. one batch of cookies takes 2.5 cups of flour. if he must save 6 cups of flour for other baking, write and solve and solve an inequality to determine how many batches of cookies he can make. Interpret the solution.

Answers

Final answer:

Corey can make at most 4 batches of cookies with the 10 cups of flour available for cookie making, after reserving 6 cups for other purposes.

Explanation:

To determine how many batches of cookies Corey can make, we need to write and solve an inequality. Corey has 16 cups of flour and needs to save 6 cups for other baking, leaving him with 16 - 6 = 10 cups of flour to use for cookies. Each batch of cookies requires 2.5 cups of flour. Let the number of batches be represented by b. The inequality will then be:

2.5b ≤ 10

To solve for b, we divide both sides of the inequality by 2.5:

b ≤ 10 / 2.5

b ≤ 4

This means Corey can make at most 4 batches of cookies with the flour he has, after setting aside 6 cups for other baking purposes.
